printer.vbs - vbscript script by ActiveXperts Software
printer.vbs checks whether a printer is up and running.
Use printer.vbs directly from ActiveXperts Network Monitor; in the Manager's 'Monitor' menu, select 'New Check (Script)' and select printer.vbs. Configure the required parameter, or press 'Load a working sample'.
In ActiveXperts Network Monitor, Administrators can use three different scripting languages: Powershell, VBScript and SSH.

' Description:
' This function checks if the printer, indicated by strPrinter, is up and running on
' the machine specified by strHost.
' Parameters:
' 1) strHost As String - Hostname or IP address of the computer you want to check
' 2) strAltCredentials As String - Specify an empty string to use Network Monitor service credentials.
' To use alternate credentials, enter a server that is defined in Server Credentials table.
' (To define Server Credentials, choose Tools->Options->Server Credentials)
' 3) strPrinter As String - Name of the printer
' Usage:
' CheckPrinter( "<Hostname | IP>", "<Empty String | Server>", "<Printername>" )

' CheckPrinter( "localhost", "", "HP LaserJet 2300 Series PS" )
